 Re: 2 issues in ISP redundancy
this seems to be a DNS issue. whatever, the internet should know how to send the request of my domain name to my DNS server which will sit behind my fW. but my DNS server which has 1 IP from each ISP might have to register on internet DNS servers(which may hold two records of my DNS server, each for an ISP's IP), then how can the internet servers know which IP to send the request to? ISP1' or ISP2's IP for my DNS server?
sorry that i am a bit new to internet DNS ? |
